Steel slag preheating furnace

Technical Field

the utility model relates to a steel slag preheating furnace, which belongs to the technical field of steel slag treatment equipment in the metallurgical industry.

Background

steel enterprises can produce a large amount of steel slag in the production process of steel making and steel rolling, and the steel slag is a slag iron solid waste mixed by iron, cement, soil, sundries and the like. Generally, a steel mill sorts out large iron blocks with irregular sizes of more than 700 mm-800 mm, the iron blocks are physically beaten and cut for direct recycling, and the iron blocks smaller than the sizes are delivered to a solid waste treatment manufacturer for slag-iron separation and purification.

After the slag and iron are separated, the steel slag after purification treatment needs to be heated to a certain temperature, and then various slag and iron blocks with different shapes are rolled into a certain shape so as to be convenient for storage, transportation and use in the steel-making process.

At present, a traditional steel slag heating furnace usually adopts a tunnel kiln or a rotary kiln, materials are heated by the tunnel kiln, and the materials are heated unevenly, so that the forming effect of the steel slag is influenced; the material is heated by the rotary kiln, overturns along with the rotation of the roller, and is heated by spraying and burning the material into the roller through the burner. The rotary kiln has the advantages that materials are turned over only by the rotation of the roller, the material turning effect is poor, and the vibration noise of equipment is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a slag preheater, the material upset is effectual, is heated evenly, can reduce equipment moreover because the noise that the vibration produced, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

The utility model provides a slag preheater, contains fixed bolster, adjustment support, pan feeding mouth, cylinder, insulating brick, spiral turner, motor, combustor, discharge gate and ring gear drive mechanism, and the adjustment support passes through the bolt fastening on the fixed bolster, and the cylinder rotates to be connected on the adjustment support, and the motor passes through ring gear drive mechanism to be connected with the cylinder drive, the cylinder is the slope form, and the higher one end of cylinder is equipped with the pan feeding mouth, and the lower one end of cylinder is equipped with combustor and discharge gate, the flame of combustor sprays along the axial of cylinder, and the inside of cylinder is equipped with insulating brick and spiral turner, spiral turner is the heliciform structure that comprises a plurality of interconnect's spiral turner block.

The section of a spiral turning block in the spiral turning device is parallelogram, and a plurality of spiral turning blocks are welded with the inner wall of the roller together through steel connecting rods to form a spiral structure.

The gear ring transmission mechanism comprises a large gear ring fixed on the roller and a small gear ring meshed with the large gear ring, the small gear ring is fixed on an output shaft of the speed reducer, and the motor is in driving connection with the speed reducer.

Adopt the utility model discloses, the motor passes through ring gear drive mechanism and drives the cylinder and rotate on the adjustment support, and the material gets into the cylinder from the pan feeding mouth in, the material is under spiral tripper's effect, and axial motion is made while overturning, and the hot gas flow of combustor spouts to the pan feeding end from the discharge end of cylinder simultaneously, and the material flows from the discharge gate after contacting with the hot gas flow and being heated in the cylinder.

The utility model has the advantages that: the material upset is effectual, is heated evenly, can reduce equipment moreover because the noise that the vibration produced.
